We report (bis)aniline 4 which contains a central viologen and its self-assembly with aldehyde 5 and Fe(OTf)2 to yield tetrahedron 6. Complexation of 4 with CB[7] in the form of CB[7]?4?2PF6 allows the preparation of assembly 7 which contains 1.95 mechanically interlocked CB[7] units. Assemblies 6 and 7 are hydrolytically unstable due to their imine linkages. Redesign of our system with water stable 2,2?-bipyridine end groups was realised in the form of ligands 11 and 16. Self-assembly of 11 with Fe(NTf2)2 gave tetrahedral MOP 12. Isomeric ligand 16 underwent self-assembly with Fe(OTf)2 to give cube 17. Precomplexation of ligands 11 and 16 with CB[7] gave the acetonitrile soluble CB[7]?11?2PF6 and CB[7]?16?2PF6 complexes. Self-assembly of CB[7]?11?2PF6 with Fe(OTf)2 gave tetrahedron 13 which contains 1.8 mechanically interlocked CB[7] units. Self-assembly of CB[7]?16?2PF6 with Fe(OTf)2 gave cube 13 which contains 6.59 interlocked CB[7] units.

The synthesis and photophysical properties of 1 and 2, two Ru(ii)-polypyridyl based-1,8-naphthalimide Troeger's bases, are described; these were found to stabilize double stranded DNA, undergo rapid cellular uptake, displaying good luminescence without affecting cell viability even after 24 hours of incubation.
